Title: Innovations of Mauro Erba
Introduction
Mauro Erba is a notable inventor based in Locarno, Switzerland. He has made significant contributions to the field of electrical discharge machining, holding 2 patents that showcase his innovative approaches to workpiece cutting and current supply devices.
Latest Patents
One of Mauro Erba's latest patents is a "Method for the initial cutting of a workpiece by electrical discharge." This method involves the initial cutting of a workpiece using a wire electrode, where the specific cutting parameters are reduced along an introduction path in the workpiece. This reduction is done in comparison to the values of the cutting parameters for the actual cutting contour. Additionally, some of the reduced values of the cutting parameters are continuously adjusted until the intended values for the actual cutting contour are achieved.
Another significant patent is the "Current supply device for movable electrodes of spark erosion machines." This device consists of multiple individual contacts and includes leads that connect these contacts to a current generator. It features electrical components such as pulse transformers for pairwise negative feedback of partial currents, or additional impedances arranged according to a mathematical series for uniform current distribution. This device is particularly effective for transmitting high-energy short pulses, which are essential for erosive wire cutting. It operates in an almost wear-free manner and can also serve as a guide for the electrode.
